Marke board read only to certain user groups.

I have a board on my forum I wish to be made read only to all but one user group. How can I do this?

Either you have to go board level permissions board -> permissions and set it up for each group. To make them not create topics or posts

Or create a new permission profile under admin -> permissions copy the read only permission then modify the permission set to allow certain membergroups to post

Thankyou
